Fifteen years ago Texas Instruments entered with the TI-1766 the market of LCD-calculators powered by solar cells. We found a lot of different designs with the TI-1766 II, TI-1766 III and this TI-1766+. But none in the line got before a tiltable display like the TI-1768 and TI-1768 II.

Dismantling this TI-1766+ manufactured in December 1998 by Inventec Corporation in Shanghai, China reveals a pretty simple design centered around an unknown single-chip calculator circuit.

With the TI-1706+ a calculator with a more traditional housing was introduced.
